[promitheus]

Hi,

I am trying to make a new crossover for some old KEF drivers I have but I can´t find data for the T-52 Tweeter from KEF.
If anybody has any info or the Thiele Small parameters please help.

Greetings

email me and I will send you a copy of the datasheet.

Does anyone know the differences between The KEF T-52 and the much older T-15? I know that the earlier one was rear mounted and the later front mounted but the actual domes look very similar from the outside.
